How to Determine the Aggregate Crushing .

Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.

Crushing work index Calculation - Crushing, .

The laboratory CWi value of 27.4 (metric) is almost within 4.5 units of the 22.4 value I calculated, so what you are observing is probably the natural variation in the crushing test. So there is nothing wrong with your calculation, and the variation between the laboratory test and your observation of the operating crusher is within the normal range of variation for this calculation.
